Application filed December 11. 1912,

*To all whom it may concern:

Be it known that 1, JOHN D. LnAri nnr, a citizen ofthe United States,residing at Harrisburg, in the county of Dauphin and State ofPennsylvania, have invented new and useful Improvements in Bean and PeaHullers of which the following is a specification.

This invention relates to an improved bean and pea huller of ahand-operated type and constructed particularly for household use.

The main obj eet of the present invention is the provision of expert orbean huller in which the peas or beans may be continuously fed in bulkand are properly and effectively hulled, the pods and refuse beingdelivered in one direction and the peas and in another.

A "further object of the invention is the provision of hulling mechanismwhich is so constructed as to insure a proper hulling of the pea or beanwithout regard to the position in which the 511111815 ted to themechanism and without liability of crushing or breaking the peas orbeans.

The invention in its preferred form of details will be described in thefollowing specification, reference being had to the ac coinpanyingdrawing, in which:

Figure 1 is a perspective view of the inn proved huller. Fig. 2 is avertical longitudinal section of the same. Fig. 8 is a transversevertical section of the same taken Fl Al 3 is a front elevation. Fig. 5is an enlarged perspective view of the ,hulling rollers.

Referring particularly to the accompanyingdrawings, the improved hulleris made up of two sections. an upper section 1 and a lower section Thesections are hingedly connected at one end; as at 3, and provided at theopposite end with spring adjusting means including a spring member athaving a ringat one end to engage a hook 5 carried by the upper section1 and connected at theoppositeend to a fitted bolt 5 passing through aneye (3 on the opposing member and engaged by a wing nut 7 below theeye.-

By this means the forward ends of the sections are held together in amore or less yieldalole manner, the pressure of the yielding connectionbeing adjustable, as will be obvious. The upper section ,includes sideboards 8 arranged in spaced parallel relation and when the sections areassembled in Specification of Letters Patent.
